Abstract
The utility model relates to a sewing machine holding tool for the computerized knotting, comprising the master element of the holding tool and a presser foot which can be separated. The lower part of the master element of the holding tool and the upper part of the presser foot form a dismountable connection through the inserting mode. The master element of the holding tool is a universal element which is fixed without changing. The different patterns can be sewed only through changing the presser foot, and thus the producing cost of the holding tool is greatly economized. The method of changing the presser foot is easier than the method of changing the whole holding tool, and thus the using cost of the holding tool is greatly reduced.
Description
Technical field
The utility model relates to the parts of computer knotting Sewing machines, specifically is meant the signature tool that is used for computer knotting Sewing machines force feed cloth mechanism.
Background technology
Computer knotting Sewing machines is the indispensable and commonly used special equipment of clothes processing enterprise, LK3-B430E type computer knotting Sewing machines as the production of Japanese brother company, this machine only is equipped with horizontal knotting program, can only BAR-TACK shape tie, and other styles of sewing then will be acquired the equipment of respective model.Along with the further exploitation of software, the function of computer knotting Sewing machines is further expanded, and can finish how different styles, and in order to make different styles, its cloth presser must be changed different signature tools.
With reference to Fig. 1, three-dimensional exploded view for original cloth presser, this cloth presser comprises homework binder pedestal 1, a left side, right homework binder shadoof 21,22, tool 5 is given as security on a left side, the right tool 6 of giving as security, compression spring assembly 3, a left side, right homework binder shadoof 21, the both sides of homework binder pedestal 1 are fixed at 22 middle parts respectively rotationally by a homework binder axle 20, the head 4 of homework binder pedestal 1 is provided with two chutes 41 longitudinally, 42, two chutes 41,42 rear side is respectively equipped with one can be for a left side, right homework binder shadoof 21,22 front end is in the groove 410 that wherein moves up and down, 420, this left side, the right tool 5 of giving as security, 6 include the slide block that is positioned at the top 51 that fuses, 61 and be positioned at the bottom presser feet 52,62, tool 5 is given as security on a left side, the right slide block 51 of giving as security tool 6 tops, 61 are slidedly arranged on two chutes 41 longitudinally respectively, in 42, and be sheathed on a left side, right homework binder shadoof 21,22 front end, can slide up and down with it, compression spring assembly 3 is located at a left side, right homework binder shadoof 21, between 22 rearward end and homework binder pedestal 1 rear lower.
During work, power set force in left and right homework binder shadoof 21,22 latter halfs with it to pressing down, the front end of left and right homework binder shadoof 21,22 is upwards mentioned left and right signature tool 5,6; Power set are decontroled left and right homework binder shadoof 21,22 latter halfs, and under 3 effects of compression spring assembly, left and right homework binder shadoof 21,22 latter halfs are upturned, and the front end of left and right homework binder shadoof 21,22 is depressed left and right signature tool 5,6 downwards.
It has following shortcoming as can be known by above-mentioned description to existing computer knotting Sewing machines cloth presser: at first, it is given as security tool and is made of superposed slide block that fuses and the presser feet that is positioned at the bottom, when changing presser feet, must integral body change together, and superposed slide block will slide up and down in chute, its machining accuracy and surface smoothness are had relatively high expectations, so the cost of integral replacing signature tool is higher; Secondly, change and give as security instrument and the technical professional that tool needs special use, the assembly and disassembly methods of giving as security tool is numerous and diverse.
The utility model content
The utility model provides a kind of computer knotting Sewing machines to give as security tool, and its main purpose is will change whole signature tool when overcoming original signature pin changes and the signature tool production cost height that brings, use cost height, shortcoming that the replacing method is numerous and diverse.
The utility model adopts following technical scheme: computer knotting Sewing machines is given as security tool, and this signature tool comprises separable signature tool main part and presser feet, gives as security between tool main part bottom and the presser feet top and forms detachable connection by inserting mode.Therefore, making different styles only need change presser feet and get final product, can immobilize and give as security the tool main part, become a general part, thereby reduce cost greatly, and the method for changing presser feet is much simpler than changing whole signature tool, give as security the connecting pin that the tool main part comprises slide block and is connected in the slide block below, the bottom surface of this connecting pin is provided with a jack, the presser feet back side edge extends back and forms an arc connecting portion that upwards arches upward, this arc connecting portion rearward end extends upward and forms a pin, this pin is inserted in the aforesaid jack, the sidewall of the jack of connecting pin bottom is provided with a spring leaf tenon, and the side of described pin offers a V-shaped groove that matches with this spring leaf tenon, and pin was fixed in the jack by this V-shaped groove and cooperating of this spring leaf tenon.
Aforesaid connecting pin is setovered forward with respect to slide block.
By above-mentioned description to the utility model structure as can be known, compare with prior art, the utlity model has following advantage: one, give as security the tool main part and be the fixing general part that need not change, make different styles and only need change presser feet, saved the production cost of giving as security tool greatly; Two, the method for changing presser feet is much simpler than changing whole signature tool, thereby greatly reduces the use cost of giving as security tool.
